BST23C712V from BORN, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | bidirectional | Connected to one RS-485 differential data line; the internal TVS has a 12 V reverse stand-off (working) voltage and clamps positive spikes above 12 V and negative spikes below -7 V. |
| 2 | I/O2 | bidirectional | Connected to the other RS-485 differential data line; the internal TVS has a 12 V reverse stand-off (working) voltage and clamps positive spikes above 12 V and negative spikes below -7 V. |
| 3 | GND | power_in | Ground pin with a 7 V TVS working voltage, connected to ground in the RS-485 application, providing the negative-side (-7 V) protection path for pins 1 and 2. |
